Abstract (en)
[origin: WO2020234224A1] The invention relates to a steering column (1) for a motor vehicle, comprising a casing unit (3) in which a steering spindle (4) is mounted so as to be rotatable about a longitudinal axis (L) extending in the longitudinal direction and which has at least two steering column tubes (31, 32, 33) guided adjustably relative to each other in the longitudinal direction and having a polygonal cross-section, wherein rolling elements (7, 8) having a rolling element radius (k) are arranged between the steering column tubes (31, 32, 33) in raceways (34, 35, 36, 37) so as to be able to roll in the longitudinal direction, wherein at least three raceways (34, 35, 36, 37) are distributed over the circumference. In order to enable greater rigidity and a compact design, according to the invention the center points (K1, K2) of the rolling elements (7, 8) which can roll radially on the outside of a steering column tube (32, 33) have a radial distance (a, b) smaller than or equal to the rolling element radius (k) from an envelope circle (90, 93) which circumscribes the steering column tube (32, 33) on the outside of which the rolling elements can roll.
